Reflective Knowledge: Confucius and Virtue Epistemology

Most of sScholars have typically regarded Confucius as an ethical thinker broadly construed and not as an epistemological thinker. This paper seeks to overturn that view and, in doing so, has three basic goals. The first goal is to make the case that Confucian thought of the Analects is of epistemological significance. Goal two is to locate the significance of the Confucian thought within epistemology while accounting for the past overlooking of this significance. The third goal is to show that the Confucian thought is not only of epistemological significance, but that it can make a contribution to progressing contemporary epistemology

Discretization error cancellation in the plane-wave approximation of periodic Hamiltonians with Coulomb singularities

In solid-state physics, energies of molecular systems are usually computed with a plane-wave discretization of Kohn-Sham equations. A priori estimates of plane-wave convergence for periodic Kohn-Sham calculations with pseudopotentials have been proved , however in most computations in practice, plane-wave cut-offs are not tight enough to target the desired accuracy. It is often advocated that the real quantity of interest is not the value of the energy but of energy differences for different configurations. The computed energy difference is believed to be much more accurate because of `discretization error cancellation', since the sources of numerical errors are essentially the same for different configurations. For periodic linear Hamiltonians with Coulomb potentials, error cancellation can be explained by the universality of the Kato cusp condition. Using weighted Sobolev spaces, Taylor-type expansions of the eigenfunctions are available yielding a precise characterization of this singularity. This then gives an explicit formula of the first order term of the decay of the Fourier coefficients of the eigenfunctions. It enables one to prove that errors on eigenvalue differences are reduced but converge at the same rate as the error on the eigenvalue.Comment: 14 pages, 3 figures, improved result on main theorem, corrected typo

The Awareness of cultural orientations in culturally responsive education for Korean American students

It is important for teachers to be aware of the cultural backgrounds of students and their family in order to provide culturally responsive instruction and counseling. Most teachers may identify Asian ethnicities due to their distinguishable physical or behavioral characteristics but they may not know how Asian Americans have changed their cultural value and legacies. To examine cultural orientation, the Korean American Acculturation Scale (KAAS), which consists of behavior and cultural value orientations, was administered to 466 Korean American students. The result indicated that the most recent generations were less behaviorally oriented to Korean culture and more disoriented to Korean cultural value after controlling the affect of age. However, the degree of behavior and cultural value disorientation to Korean culture varied among individual Korean American students, depending on their genders and/or generations. Korean American students seemed to choose the degree and mode of their cultural orientation selectively during their acculturation

Complex regional pain syndrome in a competitive athlete and regional osteoporosis assessed by dual-energy X-ray absorptiometry: a case report.

Dual-energy X-ray absorptiometry is rarely utilized in the clinical care of patients with complex regional pain syndrome, but may be useful for the non-invasive determination of regional bone fragility and fracture risk, as well as muscular atrophy and regional body composition. This is the first report in the literature of complex regional pain syndrome and musculoskeletal co-morbidities in an athlete, and is the first to focus on dual-energy X-ray absorptiometry for the clinical assessment of complex regional pain syndrome

Resonance in the nonadiabatic quantum pumping of the time-dependent Josephson junction

In this work, we investigated the nonadiabatic transport properties of the one-dimensional time-dependent superconductor-normal metal-superconductor (SNS) Josephson junction biased by a current source and driven by a high-frequency-ac-gate-potential applied to the normal-metal layer. BCS superconductors are considered and treated with the time-dependent Bogoliubov-de Gennes equation. Using Floquet theory, we compute the transmission coefficients and the Wigner-Smith delay times as a function of the incident energy and find that they display resonances when one of the electron or hole Floquet wavevectors coincides with the bound quasiparticle state within the superconducting energy gap. The resonance varies with the phase difference between the two superconductors as a result of the bound quasiparticle level displacement. The supercurrent flowing through the SNS junction is dramatically enhanced by the resonances
